Hotch: A sniper can wait up to 72 hours without sleeping.
Mays: Seriously?
Rossi: That's part of their training. They can stay awake for 72 hours and remain completely focused on their target.
Mays: How?
Hotch: By using a mental exercise called "fantasy integration". A sniper creates a scenarios involving a target that keeps that person at the forefront of their mind.
Morgan: Often they'll imagine a place where they're with the target, doing something together that takes time. For example, building a car.
JJ: For some, the fantasy begins the minute they're assigned a target. Then nothing will distract them.

Our most basic common link is that we all inhabit this planet. We all breath the same air. We all cherish our children's future. And we are all mortal - John F. Kennedy.

Blake: Identical twins. What are the odds?
Rossi: About 3.5 per thousand. I asked Reid the same question.

We are not only our brother's keeper; in countless large and small ways, we are our brother's maker - Bonaro Overstreet

Morgan

Wallace: All I know is that when I kill or even think about doing it, I feel better.
Jesse: You don't need jail. You need help.
Wallace: Yeah? Who's going to help me?
Jesse: I am. For better or worse, we're related. Which mean it's my job to protect you.

Wallace: I know why you're doing all this.
Jesse: Really. Why?
Wallace: You want to be like me.
Jesse: No I don't.
Wallace: Then why bring me here? Why try to understand me? Why care? You want to know me so you can be me. And that's why I'm not going to leave, because I want that too.

Carla: You stopped believing me just then.
Hotch: Because you stopped telling the truth.

Carla: Why couldn't I be the perfect mom and have the perfect kids like all the other moms? I deserve that!
Hotch: Yes you do.

Jesse: I know this going to sound totally weird but I was hoping we could do this one together.
Wallace: That's not weird. That's not weird at all.

Morgan: We're looking for a Mr. Bill Robbins.
Robbins: The sun and the moon have arrived. I'm ready to join you in your golden chariot.
Reid: We'd like to ask you a few questions, if you have a moment?
Robbins: Yes. Yes, yes, yes, yes, yes yes! My life is the answer to your questions.

They mess you up, your mom and dad. They may not mean to, but they do. They fill you with the faults they had, and add some extra, just for you - Philip Larkin.

Hotch

JJ: We were this close to going to Ocean City, then I get the text.
Reid: I was in the middle of calculating force times distance times the coefficient of friction to determine how fast I can make a hairpin turn in a Prius.
JJ: You don't have a hybrid, Spence.
Reid: I know but if I did I'd want to know.
